ESIM.DOG offers a range of unlimited‑data eSIM plans for Vietnam that are valid from 1 day up to 20 days. The data cap column lists “Unlimited”, and the plans are marked with a maximum speed ranging from 128 kbps to 1000 kbps; speeds may be throttled after the threshold defined in the provider’s fair‑use policy. Prices start at about $1.56 USD for a 1‑day plan and rise to roughly $12.10 USD for a 20‑day plan. Because the plans are unlimited, there is no hard data limit, but users should be aware that traffic may be slowed if the fair‑use policy is triggered. For the most current speed limits and any additional details, it is best to consult ESIM.DOG directly.
